The front side 30 also accommodates a display 36 of the controller 21. It is understood that the front side 30 of the housing 20 could have an opening wherein a screen of the display is positioned therein. It is also understood that the housing 20 could be formed such that it has a solid, thin layer wherein the display 36 of the controller 21 is viewable through the thin layer on the front side 30.

As depicted in FIGS. 6-12, the back side 31 of the housing 20, near the second end 24, has a protrusion 38. The protrusion 38 has a generally circular cross-section. The protrusion 38 has an enlarged rounded head and an insert that fits within the interior of the housing 20 (FIG. 12). As explained in greater detail below, the protrusion 38 is adapted to be inserted into a receiver or aperture 40 in the carrier 18.

As further shown in FIGS. 6-12, the components of the controller 21 are contained within and supported by the housing 20. The controller 21 includes various electrical components allowing the controller 21 and device 16 to act as an interface device wherein the device 16 can communicate with the sensor 12, record and store data relating to athletic performance, other time information, as well as upload performance data to a remote location or site as described in greater detail below. The controller 21 further includes the first input 32 and the second input 34. The controller 21 further includes the display 36 that is positioned on the front side 30 of the housing 20. It is further understood that the controller 21 is operably connected to the connector 23 of the housing.

As shown in FIGS. 2-4 and 12-14, the carrier 18 is generally in the form of a wristband 18 having a central portion between a first end and a second end. The wristband 18 may include a first member 18 a and second member 18 b generally molded or connected together. The wristband 18 is flexible to fit around a user's wrist. The wristband 18 has receiving structures for connection to the device 16. The carrier 18 includes a protective sleeve 60 proximate the central portion for receiving the connector 23 of the housing 20. The protective sleeve 60 has a generally contoured surface. As shown in FIG. 13, the sleeve 60 may have internal structure for assisting in securing the connector 23. Also at the central portion, the carrier 18 has an aperture 40 dimensioned to receive the protrusion 38 of the wearable device 16.

As further shown in FIGS. 4 and 13-16, the wristband 18 has a removable closure 70 used to fasten the wristband 18 to a wrist of a user. To this end, the removable closure 70 cooperates with a plurality of holes in the wristband 18. The removable closure 70 has a plate member 72 and a plurality of posts 74 extending generally in a perpendicular direction from the plate member 72. In the exemplary embodiment depicted in FIG. 15, the plate member 72 has two posts 74. Each post 74 has an insert 76 that is pressed on or snap-fitted onto the post 74. Each insert 76 is spot welded to the plate member 72. Other connection methods are possible. A gap is maintained between an inside surface of the plate member 72 and a bottom surface of the post 74. In addition, each post 74 has an annular channel 78 around a periphery of the post 74.

To wear the wristband, first the removable closure 70 is connected to one end of the wristband strap 18 wherein a pair of holes is provided to receive the posts 74. The wristband 18 fills the gap. The wristband 18 is positioned around the user's wrist and the posts 74 are inserted into the holes provided on the other end of the wristband 18 as can be appreciated from FIG. 2. The portion of the wristband 18 proximate the holes fits within the annular channels 78 of the posts 74. With the use of a pair of posts 74, the removable closure 70 allows for a secure connection and greater flexibility in connection providing for a greater adjustment to accommodate for a range of wrist sizes.

Additionally, the plate member 72 can have indicia 73 thereon. The plate member 72, when attached to the wristband 18 faces away from the wristband 18 wherein the indicia 73 can be viewed by others. Because the removable closure 70 is easily removable, the closure 70 can be used as a memento, different closures can be provided and used with the wristband 18. Thus, removable closures 70 having different indicia can be provided and used as a keepsake, memento, or a reward for accomplishing a goal, participating in a race, or otherwise achieving a certain level of fitness. Indicia can take various forms including wording, graphics, color schemes, textures, or other designs etc.

As discussed, the wearable device 16 is removably connected to the carrier 18. The connector 23 is inserted into the sleeve 60 of the carrier 18, and the protrusion 38 is placed into the aperture 40 of the carrier 18. The enlarged head of the protrusion abuts against the wristband 18 to retain the device 16 onto the wristband 18. This provides for a wearable device 16 that can be disconnected from the carrier 18 when desired and plugged into a computer as discussed in greater detail below. It is understood that detent structures can be provided between the connector 23 and sleeve 60 of the various different embodiments disclosed herein.

It is understood that the device 16 has general functions such as keeping the time of day just like a convention watch device. It is further understood, however, that the device 16 can be used as part of the athletic performance monitoring system 10. For example, a user wearing shoes having the sensor 12 mounted therein can use the device 16 to wirelessly communicate with the sensor 12 and monitor performance such as for running.

As can be appreciated from FIGS. 17-27, when the user wants to start a run, the user must first allow the sensor 12 to communicate with the wearable device 16. To do this, the user pushes and holds the first input 32 via the pushbutton 33 on the front side 30 of the housing 20. While the user holds the first input 32, the display 36 exhibits scrolling zeros as the wearable device 16 searches for the sensor 12. Once the sensor 12 is located, as shown in FIG. 18, the display 36 indicates that the wearable device 16 is ready to start by displaying a shoe symbol 62 in the upper left corner and a blinking underline 64. The user then pushes the first input 32 again to initiate the recording of the run. The wearable device 16 then records various information during the run such as elapsed time as shown in FIGS. 19 and 20. A bottom line on the display 36 animates back and forth to indicate that the device 16 is in the record mode. During the run, the user can toggle through the distance ran, current pace, elapsed time, and calories spent by pushing the second input 34. To stop recording, the user pushes the first input 32. After the device 16 is stopped, the user can review the last distance run (FIG. 22), average pace, calories burnt, average calories burnt per minute, miles ran per week (FIG. 23), total miles (FIG. 24), and the time of day of the run (FIG. 25) by pressing the second input 34, which toggles through these values.

The device 16 has additional capability for uploading of the recorded data to other remote locations such as locally on a personal computer or a remote website for further display, review and monitoring. To this end, it is understood that the controller 21 of the device has an appropriate user interface wherein a user can download appropriate software via a computer from a remote location. The device 16 is removed from the carrier 18 wherein the protrusion 38 is removed from the aperture 40 and the connector 23 is removed from the sleeve 60. As shown in FIGS. 26 and 27, the connector 23 is then plugged into the standard USB hub/port on a computer C. Once the appropriate software is installed, the application will commence with device 16 still being plugged into the computer. The software application may prompt the user through a device set-up procedure (time, calibration etc.). At this point, if desired, the user can upload the performance data from the run to a remote website location such as one dedicated to monitoring athletic performance. The user can log onto the particular website via a standard web-browser and upload the performance data from the device 16 to the website. As shown in FIG. 27, the user can then review data relating to the run. The website may display the data in graphical form. Other features can also be provided to assist the user in utilizing the data recorded by the device. Additional registration features can be provided with the website wherein additional features can be provided to the user for use with the device 16.

The user interface associated with the controller 21 of the device 16 can provide additional functionality to the user. The software can include a self launching feature, which automatically launches the software once the wearable device 16 is connected to a computer containing the software. Once the program is launched, the software will also automatically download the data from the device 16 to the computer and transfer the data to a web server and to the website discussed above. The software can also detect the device class connected to the port and configure the correct application for that specific device. For example, there may be wearable devices 16 having different configurations, or technical capabilities, and thus may be classified differently. The software can change the feature set of the fitness activity recording of the wearable device 16 connected to the port of the computer. After the wearable device 16 is disconnected from the computer, the software automatically exits. The user interface may also be configured to allow a user to selectively activate and de-activate features according to the preferences of the user. The user may also be able to modify software associated with the device.

The software has an extremely simple calibration method and user interface. For example, it is very simple to calibrate distance measurements onto the device. A calibration module associated with the software as well being configured to be operably associated with the device assembly 14 and sensor 12 is described in greater detail below. The software can also track motivational information among several classes of fitness activity recording devices. For example, the user can set weekly goals and the software can track the user's progress with these goals. The user can also use multiple devices, such as an audio player having a suitable interface device, other types of sport watches etc., along with the device of the present invention, and the software will accumulate the weekly and overall total distance recorded by all of the devices. Thus, the data is kept synchronized over multiple devices.

The website can additionally have a guest log in, which allows the user to upload data automatically from the device without requiring the user to register. This feature allows the user to use the website without giving personal information. Later, if the user decides to register the device, a unique PIN number associated with each wearable device is matched up with registration information automatically.

As discussed, the wearable device assembly 14 utilizes its housing 20 to support the controller 21 and associated components. In one exemplary embodiment, the housing 20 has unique structures to enhance its functionality. Because the device 16 is used in fitness activities, there is some chance that the device 16 can be subject to water or moisture such as perspiration. The housing 20 is designed to be water-resistant to protect components of the controller 21.

As shown in FIGS. 28-36, the housing 20 has a first member 20 a and a second member 20 b. The first member 20 a is joined with the second member 20 b to form the housing 20. The members 20 a, 20 b are generally formed from plastic in an injection molding process. It is understood that the housing 20 can be constructed from other suitable materials.

As discussed, the front side 30 of the housing 20 has a first push button 33 that is flexible and cooperates with the first input 34 of the controller 21. In an exemplary embodiment, the first push button 33 is co-molded with the first member 20 a. The co-molding process allows for the combination of a hard plastic portion with a soft elastic polymer portion. The hard polymer portion provides the controller 21 with adequate protection from shock or other forces, and the soft elastic polymer portion of the push button 33 allows the user to depress the first push button 33 to actuate the first input 32. With the co-molding process, the first push button 33 is integral with the housing 20. Together the hard polymer portion and the soft elastic polymer portion provide for an adequate sealed structure of the housing 20 around the first push button 33 of the housing 20.

As depicted in FIGS. 32-36, the second member 20 b of the housing 20 is formed in an injection molding process having the connector 23 and a U-shaped groove 80. The connector 20 has a plurality of leads or contacts 81 associated therewith making up the USB connection. The connector 23 is integrally molded with the remaining portions of the second member 20 b to eliminate the need for a separate connection and seal around the connector 23. The leads 81 can have break-off portions to assist in the molding process. As further shown in FIGS. 27-36, the U-shaped groove 80 is molded into the second member 20 b and extends around the full periphery of the second member 20 b. The second member 20 b also includes locating ribs for assisting in providing an accurate fit between the first member 20 a and the second member 20 b.

To join the first member 20 a and the second member 20 b, the necessary components of the controller 21 are suitably mounted in and connected to the second member 20 b. The U-shaped groove 80 is filled with an epoxy 84 (shown schematically in FIG. 28). A flexible epoxy suitable for bonding injection molded parts is used. The first member 20 a is then placed onto the second member 20 b using the locating ribs and the epoxy is allowed to set. Once the epoxy sets, a flexible and water resistant seal is formed between the first member 20 a and the second member 20 b.

As further shown in FIG. 31, the second input 32 has a second push button 37 associated therewith. The second push button 37 has an actuator post 39 extending therefrom and through the side opening of the housing 20. It is understood that the first member 20 a and second member 20 b of the housing 20 are molded to define the side opening. The side opening narrows down to a post opening 41 adjacent an interior of the housing 20 for communication with further components of the second input 34. The actuator post 39 has an annular groove 43 around a periphery of the post 39. Additionally, a sealing member such as an o-ring 88 surrounds the actuator post 39 in the annular groove 43. The o-ring 88 is sized to seal against the interior surface defined by the post opening 41. The o-ring 88 provides an adequate seal such that debris, water or other moisture cannot enter the housing 20 through the side opening in the housing 20.

This overall arrangement provides for a robust wearable device. The wearable device housing structure can absorb the shocks and impacts of running such that the controller can operate smoothly. Additionally, the wearable device housing structure prevents debris, water or other moisture from ingress into the interior of the housing where it could contaminate the controller 21 and adversely affect operability. In one exemplary embodiment, the wearable device 16 is water-resistant to approximately five atmospheres of pressure.

FIGS. 37-85 disclose general operational features of the wearable device assembly 14. Included in these features is a calibration module associated with the software and the wearable device assembly 14 and sensor 12.

The figures disclose procedures for the user in the initial setup of the wearable device assembly 14 as well as getting the user started in recording athletic performance data such as run or walk data. This covers the procedures undertaken by the user in getting started with the assembly 14. Procedures for using the Settings Window, the User Tab and Time Tab are also described.

FIGS. 51-53 disclose additional calibration procedures for the assembly 14. While the wearable device assembly 14 is generally accurate for most users without calibration, utilizing the available calibration procedures can improve the accuracy of the assembly 14 for a user's particular running or walking style. The calibration procedure is performed for running or walking separately. As discussed above, the system utilizes associated software such as when uploading athletic performance data to the remote site. The wearable device assembly 14 and software may then have a calibration module associated therewith for a user to implement the calibration procedures. The calibration module is operably associated with the assembly 14 and can reside at various locations including on a desktop utility associated with the user's computer C or at some other remote location such as the remote site as described above.

The user first enables the assembly 14 for recording data as described above and establishes a calibration run or walk by running or walking a known distance at a steady, natural pace. When referring to a run by the user herein, it is understood that this could be either a run or a walk by the user. It is important the distance be measured accurately and, therefore, a running track may be useful for such calibrations as distances are typically marked and are accurate. In one exemplary embodiment, the run or walk is between 0.25 and 1.25 miles. It is understood that the assembly 14 records data from the sensor based on factory set parameters associated with the sensor 12. The assembly 14 records the athletic performance of the user in the form of a run or walk and records a measured distance of the distance traversed by the user. The measured distance corresponds to a measured value and may be recorded in different units such as miles or kilometers. The device 16 is then removed from the assembly 14 and the USB plug is inserted into the USB port on the user's computer C. It is understood that the computer has all of the necessary software downloads etc, for operation as described above. Utilizing the user interface on the computer, the user clicks on the “i” button in the main window. A Settings Window appears and the user clicks on the calibration tab as shown in FIG. 52. A useable run or walk will be displayed in the window including distance and date as shown in FIG. 53. It is understood that a run or walk will not be displayed if there is no usable run or walk, such as if the run or walk was for an incorrect distance or if the user mixed running with walking. In this case, the user interface will provide the message, “no walks or runs were useful” wherein the user must repeat the run or walk until successful.

As shown in FIG. 53, the run or walk can easily be calibrated. For example, if the user knows the run or walk was exactly 1 mile, which represents the known distance, but the Calibration tab setting shows that the user ran or walked just over or just under a mile, which represents the measured distance/value recorded by the assembly 14 in communication with the sensor 12, the user can make adjustments to the measured distance/measured value. As shown in FIG. 53, the user can manually adjust the measured value using the “up” and “down” buttons so that 1 mile is shown. Thus, the calibration module allows the user to adjust the measured distance to correspond to the known distance. If the distance shown is 1 mile, the user does not need to change the display. The user clicks the “Done” button wherein the changes are saved, the Settings Window is closed and the user is taken back to the main Utility Window. This calibration adjustment is thus saved to the assembly 14 wherein when the assembly 14 is recording data with the associated sensor 12 in subsequent athletic performances, the assembly 14 will record data based on the calibration adjustment recorded and saved by the user. Accordingly, the assembly 14 will have enhanced data recording capabilities based on the user calibration performed. As discussed, the sensor 12 and/or assembly 14 will initially record data at certain set parameters and may be referred to as factory set parameters. Using the calibration module, the user can adjust the distance measured in a calibration run thus defining a modified parameter. This modified parameter is saved to the assembly 14 wherein when the assembly 14 records subsequent athletic performances, the assembly 14 records data from the sensor 12 based on the modified parameter. It is understood that the assembly 14 and sensor 12 has a calibration value for a run and a separate calibration value for a walk and thus the user must calibrate runs and walks separately. In an exemplary embodiment, the assembly 14 communicates with the sensor 12 to record run/walk data wherein it is understood that there is a linear relationship between foot contact time of the user and pace, wherein foot contact time may be considered a Y-axis value and pace may be considered an X-axis value. A run or walk can be represented by a line utilizing the line algorithm, y=mx+b, wherein m equals the slope and b equals the Y-intercept. Thus, based on the line algorithm, data is recorded according to a line having a certain slope. Once the user adjusts or modifies the measured distance to correspond to the known distance, the slope is modified according to the user adjustment. This new slope is saved wherein for subsequent performance data recordings, the assembly 14 will communicate with the sensor 12 to record data at the modified parameter or slope. Such calibration adjustment provides for enhanced data recording capabilities.

The device 16 is capable of storing calibration information for multiple sensors 12 and 13, such as if the user runs or walks in several different pairs of shoes 9 and 11, respectively (FIG. 1). In one exemplary embodiment, the device 16 can accommodate information for up to 8 sensors. Each time the user obtains a new sensor, the calibration procedure described above should be performed. If the user desires to calibrate the device 16 a second time, the user must reset the run or walk in the Calibration tab settings. The user clicks the Reset button to return the device 16 back to the original factory calibration settings. This improves the accuracy of subsequent calibrations. It is further noted that even after calibrating, the accuracy of the distance measurements may vary depending on gait, running surface, incline, or temperature. Also, calibrating a target “race pace” will provide the user better accuracy when running a race.

The assembly 14 also has further calibration capabilities to enhance overall operation. As discussed, users can access and track performance data relating to previous runs or walks. Such data is stored at remote locations such as a website dedicated to such data. In one exemplary embodiment, the overall user interface allows a user to connect a recorded run with a mapped profile. The mapped profile shows the total distance of the run and represents a known distance. When the user makes this connection, the distance of the run can be compared to the measured distance of the run. If these values are different, the user can be prompted to use the mapped distance to calibrate the device 16. Additional windows or buttons can be provided to effect such a change.

In another alternative calibration procedure, the overall user interface allows a user the option to “name a run.” When multiple runs (e.g., three runs in one exemplary embodiment) are linked to the same run name, the user interface can use the average of the multiple runs and compare this value to the last distance run. If these values are different, the user interface can prompt the user to use the multi-run average to calibrate the device 16. Thus the multi-run average of prior runs or walks can be used as the known distance for calibration. Additional windows or buttons can be provided to effect such a change.

FIGS. 80-85 disclose additional screen shots from the user interface associated with the calibration module of the present invention wherein a run and/or walk recorded with the assembly 14 and sensor 12 can be calibrated. As previously discussed, the assembly 14 has software operably associated therewith that includes the calibration module. As shown in FIG. 81, through the computer C, the user can click on the Calibration tab of the calibration module, wherein a Recent Runs drop down menu is displayed and a Recent Walks drop down menu is displayed. The drop down menus are populated with recent calibration-eligible runs and walks that were uploaded from the assembly 14 as described above. As shown in FIG. 82, it is understood that the drop down menus can expand as needed with up/down arrows wherein the user can scroll through the menus to select a run or walk to calibrate. In an exemplary embodiment, the date of the run or walk is listed with the measured distance adjacent to the date. As can be appreciated from FIG. 83, once a user selects a run or walk field, the other field becomes inactive automatically. Thus, as shown in FIG. 83, once the user selects the 8.23.08 run for example, the selection is highlighted and the Recent Walks field is inactive. Also, an Actual Distance field is displayed along with up/down arrows and the standards of measurement. Thus, the user can change between miles and kilometers if desired. The up/down arrows allow the user to change the Actual Distance value in increments of hundredths. Also, once the 8.23.08 run is selected, the associated measured distance, 2.10 miles, is placed in the Actual Distance field. As shown in FIG. 84, the user can click on the up/down arrows to change the measured distance to correspond to the known distance traversed by the user. As shown in FIG. 84, the user knows the known distance of the 8.23.08 run was 2.5 miles. Thus, the user clicks on the up arrow until the Actual Distance field is adjusted to 2.5 miles. Once the Actual Distance field is adjusted, the Save and Cancel buttons become active and change to a perceptively different color such as the color red. Pressing Cancel returns the user to the screen shown in FIG. 80. Pressing the Apply button enters the information into the memory associated with the calibration module thereby saving the calibration. As shown in FIG. 85, in response to pressing the Apply button, the Recent Runs field displays the 8.23.08 run with the original measured distance (2.10 miles) with the new calibrated distance (2.50 miles) next to the original measured distance. This also provides an indication to the user that this particular run was calibrated.

Consistent with the discussion above, this calibration adjustment shown in FIGS. 80-85 is saved to the assembly 14 wherein when the assembly 14 is recording data with the associated sensor 12 in subsequent athletic performances, the assembly 14 will record data based on the calibration adjustment recorded and saved by the user. Accordingly, the assembly 14 will have enhanced data recording capabilities based on the user calibration performed. As discussed, the sensor 12 and/or assembly 14 will initially record data at a certain set parameter and may be referred to as a factory set parameter. Using the calibration module, the user can adjust the distance measured in a calibration run thus defining a modified parameter. This modified parameter is saved to the assembly 14 wherein when the assembly 14 records subsequent performances, the assembly 14 records data based on the modified parameter. It is understood that the assembly 14 and sensor has a calibration value for a run and a separate calibration value for a walk. In an exemplary embodiment, the assembly 14 communicates with the sensor 12 to record run/walk data wherein it is understood that there is a linear relationship between foot contact time of user and pace, wherein foot contact time may be considered a Y-axis value and pace may be considered an X-axis value. A run or walk can be represented by a line utilizing the line algorithm, y=mx+b, wherein m equals the slope and b equals the Y-intercept. Thus, based on the line algorithm, data is recorded according to a line having a certain slope. Once the user adjusts or modifies the measured distance to correspond to the known distance, the slope is modified according to the user modification. This new slope is saved wherein for subsequent performance data recordings, the assembly 14 will communicate with the sensor 12 to record data at the modified parameter or slope. It is understood that the same procedure described above can be done for a walk as well. Such calibration adjustment provides for enhanced data recording capabilities.

In one exemplary embodiment, if the user calibrates a run/walk a second time that utilizes a common sensor, the earlier calibration will be overwritten by the subsequent calibration. The calibration module can also be configured such that subsequent calibrations using a run/walk with the same sensor can be combined with earlier calibrations. In such instances, the data can be combined wherein subsequent calibrations further enhance the calibrations.

In one or more configurations, the line algorithm or formula correlating foot contact time and pace may be modified as new information and athletic performance data becomes available. For example, as discussed herein, an initial line algorithm may be modified based on a run or other athletic activity covering a known distance. If an athlete subsequently performs additional athletic activity traversing the same or another distance, that contact vs. pace distance for that additional athletic activity may be used to modify the line algorithm. The building of the line algorithm may provide better accuracy (e.g., in the event data for a first athletic activity is an outlier). In one example, the athletic performance data of the additional athletic activity may be averaged into the line algorithm.

Additionally or alternatively, the line algorithm may be used to interpolate or extrapolate distance conversions. That is, the line algorithm may be initially generated based on a first athletic activity of a known distance (e.g., 1 mile). If subsequently an athlete performs a second athletic activity of a second measured distance, the contact information or pace data associated with the second athletic activity may be adjusted to match the line algorithm so that a calibrated distance may be determined (e.g., via extrapolation or interpolation).

With the calibration procedures described above, a user can use any run or walk for calibration, and not just a particular run completed in calibration mode. As the procedure is finalized using the personal computer of the user with user friendly prompts, it is much easier for the user to understand and have confidence in the accuracy of the assembly 14.

FIGS. 54-55 discloses Utility Menu windows. These windows, depending on the operating system, can be used as an alternate method for getting to settings, battery status and the like.

FIGS. 56-79 disclose additional operational features on the use of the wearable device assembly 14, such as use of the toggle buttons during a run as well as procedures when ending a run. For example, upon ending a run, the user can use the toggle buttons to review the data just recorded regarding the run. While the wearable device assembly 14 may be initially linked to a sensor, the assembly 14 is capable of being linked to multiple sensors. In one exemplary embodiment, the assembly 14 can link to 8 sensors. This is very helpful if the user performs athletic activity in more than one pair of shoes. FIGS. 76 and 77 provide additional information regarding the memory and battery associated with the wearable device assembly 14. FIGS. 45-49 disclose additional information regarding uploading of recorded run data to a website dedicated to tracking athletic performance.

The calibration module of the present invention can be configured to provide various additional features for enhancement of the device assembly 14.

In one exemplary embodiment, the calibration module is capable of storing multiple sets of calibration values for a user. Each calibration value is designed to be applicable to a specific pace range. The calibration module can then be configured to use appropriate calibration values depending on the pace of the walk or run of the user. Thus, as the user varies foot contact time, the appropriate set of calibration values is applied to calculate pace from the measured foot contact time. For example, the calibration information could include information for a slow pace, a medium pace and a fast pace. Based on the values read by the sensor 12, the calibration module will use the appropriate value to calibrate. Thus, if the run was done at a fast pace, the calibration module will calibrate using information corresponding to a fast pace.

As discussed above, the calibration module may be configured to store unique calibration values for each of a plurality of shoe sensors. This enables different calibrations for different shoes. For example, a user may wear different shoes for different training regimens or styles. The user interface associated with the calibration module can provide additional queries for a user to specify the type of training being performed and the calibration performed accordingly. The user can decide which runs/walks to calibrate based on which sensors were used for which runs/walks. It is understood that the software could be configured to provide a field to identify the sensor. It is further understood that even with multiple sensors, the assembly 14 will understand which particular sensor the assembly 14 is communicating with.

The calibration module may also be configured to provide certain automatic calibrations. For example, a user may participate in a performance such as a race having a known distance, e.g., a 5 k or 10 k race. The calibration module can be configured to automatically calibrate the sensor 12 at the end of the event. Thus, the actual recorded series of foot contact times can be correlated to the known distance of the overall event.

The calibration module may relate to a linear relationship between foot contact time and pace, wherein foot contact time may be considered a Y-axis value and pace may be considered an X-axis value. A run or walk can be represented by a line utilizing the line algorithm, y=mx+b, wherein m equals the slope and b equals the Y-intercept. The calibration module may be configured such that the calibration methodology alters both the slope and y-intercept values for each user for each walk or run calibration values. The calibration module may also be configured such that only the y-intercept value for each walk and run calibration value is altered.

The calibration module may also consider additional physiological traits of the user. For example, a user's shoe size, height, inseam, gender or other traits can affect optimum calibration settings. Thus, the user interface associated with the user interface may query the user to enter certain physiological traits during the calibration procedure. Additional calibration settings can then be utilized that are associated with the physiological traits. It is understood that a combination of such traits could be utilized in the calibration process. This feature can also be combined with other features described above to create an enhanced initial calibration (e.g., factory set, or “out-of-box” calibration) as well as an enhanced subsequent calibration.

As explained above, web-based map settings can be used to determine the known distance regarding a calibration walk or run. When global positioning system (GPS) data is available and determined to be accurate, the calibration module can be configured to automatically calibrate the sensor. In such fashion, the sensor 12 can be more accurate during times when GPS is not available such as during indoor activity or under heavy tree cover.

The calibration module can also be configured such that the module is operable with a sensor 12 that is linked with multiple athletic performance monitoring devices. For example, the user may use the device assembly 14 with a sensor 12 as well an additional monitoring device that is also linked with the sensor 12. The additional monitoring device could take various forms such as a traditional wristwatch having appropriate athletic functionality as described herein, a mobile phone, digital music player, or other type of mobile device. The calibration module can be configured such that the module is capable of distinguishing between different monitoring devices. Thus, if a user calibrates a run performed with a sensor 12 and the device assembly 14, and then the user performs a run using the sensor 12 with a different type of athletic performance monitoring device, the module will instruct the different monitoring device to record data based on the calibration done for the sensor 12 and the device assembly 14.
